I agree with Stop… and I take back my initial thought that the OS was Physics. A Growth of Stop puts the OS in Manipulation (if we choose Fixed Attitude for More’s MC throughline).
I think Manipulation fits well for the OS. This gives us a more refined summary of the OS, since just about everyone is trying to manipulate More into “bending to the marriage.” Nearly everyone else has already bent to it.
So we might say that the OS is “Manipulating dissenters into bending to the marriage.”
Choosing an OS Domain of Situation, with respect to our other choices, would put More in Manipulation, but it doesn’t really feel (to me) like More is trying to manipulate anyone. He’s just made up his mind and is sticking with his convictions.
